Injection molding of metal is similar to injection molding of polymer, and has been utilized to produce large quantity of small metal parts with good tolerances. How do you think that metal can be processed via injection molding?
Homework Answers
AAnswer for the given question is given below,
Metal injection molding (MIM) is technique to produce metal components by injection molding.
In this is metal powder is combined with organic binders such as Polyoxymethylene (POM).
Metal powder is produced by Gas atomization process.
Powder particle of spherical shape are preferred as they has low coefficient of inter-particle friction.
Powder combined with binders is the feedstock for the process.
Feed stock is heated and components are molded in metal injector molding press at high pressure and then binder is removed by process called debinding process.
After the debinding process the components are sintered at elevated temperatures in protected environment (vacuum) and it is seen that components get shrink after sintering process.
Hope this is helpful.
Thank you.
All the best.

Problem 1 (20 points) It has been noted that the more a metal has been cold worked, the less it strain hardens. Explain why. b) Two parts have been made of the same material, but one was formed by cold working and the other by hot working. Explain the differences you might observe between the two. c) Utilizing coldworking, a strip of metal is reduced from 40mm in thickness to 20mm; a similar strip is reduced in a similar way...

injection molding process of a vehicle hush panel. Briefly, the
process starts with material being fed into the back end of the
barrel and screw mechanism. The screw rotates and heat is added,
melting the material and moving it to the front. The molten
material is injected into a mold. The plastic is cured until it is
solidified. This constitutes a cycle. A quality engineer at the

A 500-g chunk of an unknown metal, which has been in boiling water for several minutes, is quickly dropped into an insulating Styrofoam beaker containing 1.00 kg ofwater at room temperature (20.0 C). After waiting and gently stirring for 5.00 minutes, you observe that the water's temperature has reach a constant value of 22.0C.A) Assuming that the Styrofoam absorbs a negligibly small amount of heat and that no heat was lost to the surroundings, what is the specic heat of...

Recently there has been discussion in the news about taxing junk food (soft drinks, for example) in an effort to reduce the incidence of obesity in the U.S. Do you think the demand for junk food is elastic or inelastic with respect to price. Based on your knowledge of the price elasticity of demand, do you think the deadweight loss of a soda/junk-food tax would be relatively large or relatively small? Why? Do you think taxing junk food would be...
